The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material
Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.
Answer: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels. or in materials that the consumer does not digest, or through movement

Answer: Proteins are digested within the stomach and little intestine. Protease enzymes break down proteins into amino acids.

Answer:
The answer is C. BPG aids oxygen delivery to tissues by increasing the affinity of myoglobin for oxygen
Explanation:
The 2,3-bisphosphoglycerate (BPG) which can also be referred to as the 2,3 - di phosphoglycerate , is being produced by the red cells and has the ability to deoxygenate hemoglobin. This is because , his accumulation results to a decrease in the affinity for oxygen, this means that , it will convert hemoglobin to a low oxygen affinity state.
In this case, comparing the options given, it will be concluded that, 2,3 -biphosphoglycerate {BPG} does not aids the delivery of oxygen to tissues, but decreases the affinity of oxygen, which deoxygenate hemoglobin, and causes the concentration of the carbon dioxide to increase.
